Magnesium is a naturally occurring mineral that is important for your body and brain. Magnesium sulfate (study drug) is a medication containing magnesium. It is commonly used to improve low blood levels of magnesium.

Magnesium sulfate has also proven to be successful in managing pain before and after surgery. This drug has primarily been used for pain control in patients undergoing surgery. Patients in the ICU with injuries also need good pain control.

Using magnesium may decrease the need for narcotics (pain relievers). It may also provide another non-narcotic drug for pain control.

The purpose of this study is to test the effectiveness of continuous, intravenous (into or within a vein using a needle) administration of magnesium sulfate. This will be compared to intravenous normal saline (salt solution).
This study requires

If you decide that you want to be in this study, the study doctor or member of the study staff will review with you all of the conditions that qualify or disqualify you from taking part in this study.

Before the start of treatment, you will participate in a “screening period”, when the study doctor will determine if you are able to enter the study.

You will receive one dose of study drug through an intravenous administration in a vein. You will receive the study drug within 24 hours of your hospital admission. Neither you nor the study doctor will choose what treatment you get.

You will be randomly put into a treatment group by chance to receive either: ● Magnesium Sulfate; or ● Normal Saline You will have a 50% (1 in 2) chance of receiving magnesium sulfate (study drug) and a 50% (1 in 2) chance of receiving normal saline (placebo).
